US Patent 7688412 Multi-domain liquid crystal display device

A multi-domain LCD device is disclosed, which includes a plurality of gate and data lines crossing one another on the first substrate, for defining a plurality of pixel regions. A pixel electrode is formed within the pixel region, the pixel electrode having an electric field induction window for dividing the pixel region into a plurality of domains. An auxiliary electrode is formed on the different layer from the pixel electrode, and beneath the edge of the pixel electrode. A common electrode is formed on a second substrate having a black matrix film and a color filter film. A circle type dielectric structure is formed on the common electrode in the plurality of domains, thereby obtaining wide viewing angle and high aperture ratio.
